How can we make Microsoft Teams better?

Teams Chat folder should not take up mailbox storage space or users should be able to archive it.

We have users with F1 licensing which means they only have 2GB of storage space available. now that we've implemented Teams, users mailboxes are filling up....because of the hidden and inaccessible Teams Chat folder in Conversation History. If they try to use mailbox cleanup, this hidden folder doesn't show up as an option for them to clean up or archive this folder. It's not easy for admins to access it to clear it either. This is a problem.
